Plasma display and method for driving the same

Abstract

A plasma display includes address electrodes for scanning and addressing display cells, and scan electrodes for establishing an address discharge between the address electrodes and the scan electrodes by addressing. The display also includes common electrodes for establishing a sustain discharge between the scan electrodes and the common electrodes to display an image at the display cells, and a scan driver for supplying a voltage to the scan electrodes so as to scan display cells upon addressing during divided periods. Upon addressing, the scan driver varies the potential of a scan electrode adjacent to the scan electrode that corresponds to the addressed address electrode.

1 . A plasma display, comprising: 
 a plurality of scan electrodes;    a plurality of address electrodes establishing an address discharge between said address electrodes and said scan electrodes by addressing;    a plurality of common electrodes, alternately disposed with and parallel to said scan electrodes, establishing sustain discharges between said scan electrodes and common electrodes to display an image; and    a scan driver subdividing an address period into subperiods, each subperiod scanning a group of electrodes and supplying a scanning voltage to scan electrodes so as to scan the group of the scan electrodes sequentially for addressing,    wherein, while the scanning voltage is supplied, said scan driver varies only the potential of one or both scan electrodes adjacent to the scan electrode selected for scanning to be closer to the scanning voltage than when the scanning voltage is not supplied.    
     
     
         2 . The display according to  claim 1 , wherein said scan driver varies the potential of said scan electrode, adjacent to said scan electrode selected for scanning, to the ground potential upon addressing.  
     
     
         3 . The display according to  claim 1 , wherein said scan driver varies the potential of said scan electrode, adjacent to said scan electrode selected for scanning, from a positive potential to the ground potential upon addressing.  
     
     
         4 . The display according to  claim 1 , wherein said scan driver adjusts the potential of said scan electrode, selected for scanning, to a negative potential upon addressing.  
     
     
         5 . The display according to  claim 2 , wherein said scan driver adjusts the potential of said scan electrode, selected for scanning, to a negative potential upon addressing.  
     
     
         6 . The display according to  claim 3 , wherein said scan driver adjusts the potential of said scan electrode, selected for scanning, to a negative potential upon addressing.  
     
     
         7 . A method for driving a plasma display comprising a plurality of scan electrodes, a plurality of address electrodes for establishing an address discharge between said address electrode and said scan electrode by addressing, and a plurality of common electrodes, alternately disposed with and parallel to said scan electrodes, establishing sustain discharges between said scan electrodes and common electrodes to display an image; and a scan driver subdividing an address period into subperiods, each subperiod scanning a group of electrodes and supplying a scanning voltage to scan electrodes so as to scan the group of the scan electrodes sequentially for addressing, said method comprising: 
 supplying a voltage; and    varying only the potential of one or both scan electrodes, adjacent to the scan electrode selected for scanning, to be closer to the scanning voltage than when the scanning voltage is not supplied.
